====RSIGIN - read signal (random position)====

=====Usage:=====

<code>RSIGIN <var>SIG REV L POS K D</var></code>

=====Inputs:=====

{|
|-
|SIG
|name of shell<nowiki>-</nowiki>wave-item
|-
|REV
|reverse read direction (<code>NO</code>|<code>0</code>, <code>YES</code>|<code>1</code>)
|-
|L
|frame length in samples (>=4)
|-
|POS
|read position (center of frame, 0..signal length<nowiki>-</nowiki>1)
|-
|K
|amplification factor
|-
|D
|differentiation factor (0..1)
|}

=====Outputs:=====

{|
|-
|<var>Xi</var>
|signal of channel i (L samples)
|-
|SR
|sampling rate in Hz
|}

=====Function:=====

This atom implements a signal<nowiki>-</nowiki>frame read function with random positioning. It can be used in signal processing circuits connected to an interactive graphic or control-dialog. In each cycle the signal around the position <var>POS</var> is read. To allow updates of <var>POS</var>, the input should be connected to a shell-value-item. The value of the output <var>SR</var> is set during the initialization. The input <var>REV</var> can be used to reverse the signal in time.
